TECHNICAL FIELD

The subject matter of this patent document relates to a candle devicethat use an imitation flame, and particularly, to features that producean aromatic scent.

BACKGROUND

Traditional true flame candles, when lit, provide a pleasant ambience inmany homes, hotels, churches, businesses, etc. Traditional candles,however, provide a variety of hazards including risk of fire, damage tosurfaces caused by hot wax, and the possible emission of soot. Flamelesscandles have become increasingly popular alternatives to traditionalcandles. With no open flame or hot melted wax, flameless candles providea longer-lasting, safe, and clean alternative. Such imitation candledevices often include light sources, such as LEDs, and includeelectronic circuits that control the operation the imitation candledevice.

Along with the development of new technologies, scented candles that areelectrically powered have appeared in the market. These electronicscented candles simulate a flickering flame, which plays a great role increating the proper atmosphere for the above venues and householdenvironments. In addition to their use as a decorative piece, thesecandles can provide additional practical functions such as releasing ascent by using a fan that forces the scent to a scent outlet for releaseinto an external environment. However, such electronic scented candlesoften do not produce a satisfactory scent, and are not convenient to use

DETAILED DESCRIPTION

In this patent document, the word “exemplary” is used to mean serving asan example, instance, or illustration. Any embodiment or designdescribed herein as “exemplary” is not necessarily to be construed aspreferred or advantageous over other embodiments or designs. Rather, useof the word exemplary is intended to present concepts in a concretemanner.

Imitation candle devices can simulate a real candle with a flame thatresembles a real-life flame with flickering effects using optical,mechanical and electrical components. As technologies advance, there isa demand for imitation candle devices that can provide additionalfunctions. This patent document describes imitation candle devices thatare capable of releasing pleasant scents into an external environment.

FIG. 1 illustrates an exemplary scent producing imitation candle device100 in accordance to technology disclosed herein. The device 100includes a flame element 103 and a shell 101. The device 100 alsoincludes a scent-producing mechanism positioned within the shell 101 toproduce scent and an observation window 126 for the user to see whetherthere is sufficient scent material.

FIGS. 2A-2C show some exemplary components of a scent-producingmechanism within an imitation candle device 100. In some embodiments, ascent producing mechanism includes a scent chamber 105. The scentchamber 105 includes a first channel 108 (shown in FIG. 2C) and a secondchannel 109 (shown in FIGS. 2A-2B). The first channel 108 is coupled to(or is in communication with) the air inside a fragrance container 107,and the second channel 109 is coupled to (or in communication with) thefragrance inside the fragrance container 107. As shown in FIG. 2A, thescent chamber 105 further includes a third channel 110 and a fourthchannel 111. The third channel 110 is configured to allow outside air toenter the scent chamber 105, and the fourth channel is configured tooutput a scent produced from the scent chamber 105 to the outside of thecandle device 100. In some implementations, the third channel 110 iscoupled to an air pump 106 to allow air to enter the scent chamber 105.

In some embodiments, the air pump 106 pumps air into the scent chamber105 via the third channel 110 such that the air pressure of the scentchamber 105 keeps increasing. The air in the scent chamber 105 entersthe fragrance container 107 via the first channel 108 under high airpressure such that the air pressure in the fragrance container 107 keepsincreasing as well. The fragrance in the fragrance container 107 is thentransported under pressure into the scent chamber 105 via the secondchannel 109. The high pressure produced by the air pump 106 allows thefragrance to be fully atomized. Because the air pressure in the scentchamber 105 is higher than the air pressure of the external environment,the atomized fragrance leaves the scent chamber 105 via the fourthchannel 111 dissipated outside of the candle device, thereby releasing ascent. In some embodiments, instead of having the air pump 106, a fanmay be used to supply the air to the third channel 110, and the fanproduces an air flow with a velocity that is directed into the scentchamber 105.

The air pump provides several advantageous aspects as compared to a fan.First, the air pump 106 can effectively drive a fragrance to the secondchannel 109 inside the electronic candle 100 by producing a high airpressure. Meanwhile, the high air pressure can fully atomize a liquidfragrance, which improves the aromatic effect of the fragrance. Second,the atomized fragrance is more concentrated as compared to fragrancedispersed using other mechanisms, e.g., a fan. Furthermore, the airpressure produced by the air pump 106 is adjustable, thereby allowingthe user to adjust the atomization rate of the fragrance. For example,when a fan is used to drive air flow to disperse the liquid fragrance,the magnitude and direction of its pressure on the fragrance may not beprecisely controlled even though the wind speed and direction of the fancan be adjusted. The air pump, on the other hand, can apply air pressureof different magnitudes and directions in a relatively precise manner,thereby achieving more effective control by the user.

In some embodiments, an installation lid 113 can be used to connect thefragrance container 107 to the scent chamber 105. In someimplementations, the installation lid 113 includes a fifth channel 115and a sixth channel 116 (shown in FIG. 2C), which are coupled to thefirst channel 108 and the second channel 109 of the scent chamber 105,respectively. In some embodiments, the installation lid 113 includes amount support 117 for mounting the fragrance container 107 in theinstallation lid 113. The mount support 117 is positioned on theinstallation lid 113 in a removable manner to facilitate easydisassembling of the mount support 117 from the installation lid 113when the mount support 117 needs to be cleaned. The removable connectionmechanism includes, but is not limited to, a snap connection. In someembodiments, the installation lid 113 further comprises a suction tube118 disposed inside of the mount support 117. The suction tube 118 mayextend into the mount support 117 and may be coupled to the sixthchannel 116 to guide the fragrance in the fragrance container 107 torise into the scent chamber 105 via the suction tube 118. In someembodiments, the suction tube 118 is fixed to the mount support 117through an interference fit between the end of the suction tube 118 andthe mount support 117. In some embodiments, the mount support 117includes a gasket that may be made of rubber or silica gel, such that anexcellent seal can be achieved when the fragrance container 107 ismounted onto the mount support 117. In some implementations, an elasticelement 119 is further disposed between the installation lid 113 and themount support 117. The elastic element 119 can be used to improve thetightness between the installation lid 113 and the installation. Theelastic material 119 can also reduce vibration of the installation lid113 and/or the mount support 117, thereby reducing noise. The elasticmaterial 119 may be rubber or silica gel. In some embodiments, the innerside of the mount support 117 is of a cylindrical structure andcomprises threads to facilitate the fixation of the fragrance container107 onto the mount support 117. In some implementations, the fragrancecontainer 107 has its own threads. The threads of the mount support 117allow the use of various types of fragrance containers 107 so long asthey have compatible threads, thereby improving the universality of thescent producing device. In some embodiments, the fragrance container 107may also be fixed through a snap connection. In some implementations,moreover, the threads of the mount support 117 are generally used andtherefore can fit most perfume bottles on the market, which alsoimproves the universality of the scent producing device (i.e. a varietyof general fragrance containers are compatible with the candle device).

In some embodiments, such as shown in FIGS. 7A-B, the first channel iscoupled to an air portion inside the fragrance container 107 via theconnection pipe 130B (shown in FIG. 7B). In some implementations, theopening end of the connection pipe 130B is above the surface of thefragrance in the fragrance container 107, and the second channel extendsinto a fragrance portion inside the fragrance container 107 via theconnection pipe 130A (shown in FIG. 7A). Usually, there is a smallamount of the fragrance remaining at the bottom of the fragrancecontainer 107 when the scent producing mechanism cannot produce scentbecause the fragrance is substantially consumed. When the fragrancecontainer 107 is replaced by the user, the electronic candle 100 may beinverted so that the installation lid 113 and the fragrance container107 can be disengaged together, as shown in FIG. 7B. The remainingfragrance in the fragrance container 107 then gathers at the opening ofthe fragrance container 107. Because the first channel 108 and thesecond channel 109 are coupled with the connection pipes 130A and 130B,whose openings are both higher than the opening of the fragrancecontainer 107, the perfume will not flow out via the first channel orthe second channel.

In some implementations, the first channel and the second channel arecoupled to a fragrance portion inside the fragrance container 107, asshown in FIG. 7C. The first channel and the second channel extend into afragrance portion inside the fragrance container 107 via the connectionpipe 130A and the connection pipe 130B. Usually there is a small amountof the fragrance remaining at the bottom of the fragrance container 107when the scent producing device cannot produce a scent because thefragrance is substantially consumed. When the fragrance container 107 isreplaced by the user, the electronic candle may be inverted so that theinstallation lid 113 and the fragrance container 107 can be disengagedtogether. The fragrance in the fragrance container 107 then gathers atthe opening of the fragrance container 107. Because the first channeland the second channel are connected with the connection pipe 130A andthe connection pipe 130B, whose openings are both higher than theopening of the fragrance container 107, the perfume will not flow outvia the first channel or the second channel. Meanwhile, as shown in FIG.7C, the connection pipe 130A and the connection pipe 130B extend to thebottom of the fragrance container 107. When the fragrance container 107is inclined or inverted, the air inside of the fragrance container 107moves to the bottom ends of the connection pipe 130A and the connectionpipe 130B, which can effectively prevent the fragrance from flowing outof the first channel and the second channel in a large quantity.

It is noted that the length of the connection pipe 130B may be setaccording to specific requirements, and any connection pipe 130B higherthan the bottle mouth of the fragrance container 107 shall beencompassed by the present document.

Referring back to FIGS. 2A-2B, in some embodiments, the dimension of oneend of the third channel 110 that is further away from the air pump 106can be smaller than the dimension of the remaining portion. The shape ofthe third channel 110 includes, but is not limited to, an evenly taperedcone, or a tapered extension in a cylindrical manner from the opening,such that the air flow in the air pump 106 has a further increasedvelocity when it flows out of the opening into the scent chamber alongthe third channel 110. The high-speed air flow output from the thirdchannel 110 allows the fragrance to be atomized and distributed moreevenly. In some embodiments, the air pump 106 can continuously pump at arate desired by a user. In some implementations, if a user wants theproduced scent to be lighter, the scent producing mechanism may be setto spray the fragrance intermittently. For example, the device may sprayfor five minutes (or another time duration) at every half an hour/onehour/two hour intervals. In some embodiments, a user may set the timeduration, turn-on time, and turn-off time of spraying. In someembodiments, the air pump 106 is controlled via a control circuitry(such as shown in FIG. 4 ), e.g., through a hardware circuit such as aPCB board. In some embodiments, a control program for the air pump 106may be written into a memory, and the control program can be executed bya processor to control operations of the air pump 106. In someembodiments, the air flow rate by the air pump 106 into the scentchamber 105 is greater than or equal to 1.0 L/min. In someimplementations, the air flow rate is greater than 1.2 L/min. Thevelocity of the air produced by the air pump 106 can be properlycontrolled to allow the liquid fragrance to be fully atomized while, atthe same time, preventing the fragrance to be sprayed too far, such asdirectly onto the wall of the scent chamber 105.

Referring to FIGS. 8A-B, the installation lid 113 is provided with alocking clip 121, such as a lock switch, with a corresponding lockingbase 120 (see also FIGS. 6A-B). The locking base 120 and the lockingclip 121 may be disposed on the top or one side of the installation lid113. As shown in FIGS. 8A-B, the locking clip 121 can form a snapconnection with the locking base 120. In some embodiments, the lockingclip 121 is fixed on the scent chamber 105 to form an integral part withthe scent chamber 105. In some embodiments, the locking base 120 has astructure that is wide at the top and narrow at the bottom, similar to aT-shaped structure.

Referring to FIG. 11A, in some embodiments, an installation lid 113 isplaced onto the fragrance container 107. The installation lid 113 alongwith the fragrance container 107 may, for example, be pushed into anaccommodating chamber 104 from the bottom of the electronic candle 100and snapped into the locking clip 121. If a user wants to take out thefragrance container 107, the bottom of the fragrance container 107 maybe pressed, then the installation lid 113 along with the fragrancecontainer 107 are disengaged from the locking clip 121, allowingconvenient use. In some embodiments, the installation lid 113 may beplaced onto the fragrance container 107 using other means. For example,it may be snapped into the locking clip 121 via the locking base 120.When the fragrance container 107 needs to be replaced, the fragrancecontainer 107 may be rotated by an angle such that the installation lid113 along with the fragrance container 107 are disengaged from thelocking clip 121. In some embodiments, as shown in FIGS. 7A-C, a limitprotrusion 122 is formed on a side of the installation lid 113, suchthat the installation lid 113 is installed at a fixed angle when beingplaced into the accommodating chamber 104, thereby making theinstallation easier.

It is noted that the locking mechanism is not limited to the snapconnection or the lock switch as described above. It is also noted thatthe installation lid 113 and the fragrance container 100 may beinstalled upward from the bottom.

In some embodiments, the top of the installation lid 113 includes aprotective layer for covering the fifth channel 115 and the sixthchannel 116 (such as shown in FIG. 2C). The protective layer can be madeof silica gel, rubber, or PVC film with a thickness in the range of0.1-3.5 mm. The protective layer is mainly used to prevent the fragrancefrom flowing out of the fragrance container 107 when the fragrancecontainer 107 is installed for the first time.

When the fragrance container 107 is installed for the first time, a userneeds to unscrew the lid of the fragrance container 107, and at the sametime, screw on the installation lid 113 installed with the mount support117 onto the fragrance container 107 in order to replace the originallid of the fragrance container 107. One way of installation is tovertically place the fragrance container 107 with its opening facingupwardly, and then align the accommodating chamber 104 of the electroniccandle 100 with the fragrance container 107. However, sometimes it isrelatively difficult to align the accommodating chamber 104 with thefragrance container 107.

Alternatively, the electronic candle device 100 can be inverted for theinstallation. As shown in FIGS. 14A-14D, the electronic candle device100 is inverted first, and the fragrance container 107 with theinstallation lid 113 (such as shown in FIGS. 7A-B) is also inclined orinverted. Because the installation lid 113 includes a limit protrusion122 (such as shown in FIGS. 7A-B), the fragrance container 107 can beinstalled into the electronic candle 100 only when the limit protrusion122 is aligned with the corresponding limit groove. The protrusion 122of the installation lid 113 enables the fragrance container 107 to besmoothly and precisely installed into the electronic candle 100, therebypreventing incorrect installation by the user. In addition, such asshown in FIGS. 14C-D, a prompt point or indicator 134 can be positionedon the bottom of the electronic candle 100 for prompting a user to alignthe limit projection 122 at the prompt indicator 134. The promptindicator 134 further enables the user to install the fragrancecontainer 107 easily and precisely. In some embodiments, the protectivelayer included in the top of the installation lid 113 prevents thefragrance from leaking through the suction tube 118, the fifth channel115, and/or the sixth channel 116 on the fragrance container 107. Whenthe fragrance container 107 is almost installed, the protective layerwill be in contact with the first channel 108 and/or the second channel109. The first channel 108 and/or the second channel 109 may pushthrough and penetrate the protective layer, allowing the perfume to flowout. After the fragrance container 107 is installed, consequently, thefirst channel 108 is now coupled to the fifth channel 115, and thesecond channel 109 is also coupled to the sixth channel 116. This way,leakage of the fragrance container during installation can be avoided,and normal use of the fragrance container is not affected.

Furthermore, as shown in FIGS. 14A-D, the bottom of the fragrancecontainer 107 is exposed to the outside of the electronic candle 100.Because the fragrance container 107 is typically made of a transparentmaterial, a user can observe the remaining quantity of the perfumeinside the fragrance container 107 from the bottom of the fragrancecontainer 107.

In some embodiments, any one of the first channel 108, the secondchannel 109, the third channel 110, the fourth channel, the fifthchannel 115, and/or the sixth channel 116 described above may be made ofa hard tube, a soft tube, or an elastic material 119. In someembodiments, the first channel 108 and/or the second channel 109 may bepositioned on the scent chamber 105. In some implementations, they areformed as an integral part of the scent chamber 105. The third channel110 and/or the fourth channel may be a soft tube or a hard tube, and thespecific material may be plastic, rubber, or PVC. In some embodiments,the third channel 110 and the fourth channel are fixedly disposed on thescent chamber 105. They are connected to the air pump 106 and ascent-releasing opening respectively via soft tubes. The third channel110 and/or the fourth channel may also be formed as an integral part ofthe scent chamber 105. In some implementations, the fifth channel 115and the sixth channel 116 are fixedly disposed on the installation lid113. In some implementations, the fifth channel 115 and the sixthchannel 116 may be formed as an integral part of the installation lid113. They can be made of an elastic material 119, such as rubber orsilica gel.

In some embodiments, such as shown in FIGS. 5A-C, the external side ofthe air pump 106 includes a sound insulation layer 128. The soundinsulation layer 128 may be made of sound insulation materials, such assound insulation cotton, to minimize the noise caused by the air pump106. For example, the sound insulation material can be sound insulationcotton so that the noise produced by the electronic candle 100 is lowerthan or equal to 55 dB, or lower than or equal to 45 dB. Within suchnoise limits, the produced noise has a relatively small impact on theusers. In some embodiments, the external side of the air pump 106,including but not limited to the top and/or bottom, may include ananti-vibration component(s) 129 so as to minimize the vibration causedby the air pump 106 in the electronic candle 100, thereby ensuring thestability of electrical contact and visual effect. The material for theanti-vibration component(s) 129 includes, but is not limited to, silicagel and/or rubber. In some implementations, with the anti-vibrationcomponent(s) 129, the noise produced by the scent-producing electroniccandle 100 is lower than or equal to 55 dB, or lower than or equal to 45dB. In some embodiments, simultaneous use of sound insulation cotton andan anti-vibration component(s) lowers the noise produced by theelectronic candle 100. In some embodiments, the air pump 106 and thefragrance container 107 are positioned in different chambers of thecandle device 100 respectively to avoid severe vibration caused byresonance of the air pump 106 and the fragrance container 107, therebyreducing the vibration and noise of the product and reducing disruptionto the atmosphere.

In some embodiments, as shown in FIGS. 2A-B, the scent chamber 105comprises an opening coupled to one end of the second channel 109. Insome embodiments, the dimension of the opening of the second channel 109in the scent chamber 105 is smaller than the dimension of the secondchannel 109 outside of the scent chamber 105. The shape of the openingincludes, but is not limited to, an evenly tapered cone, or a taperedextension in a cylindrical shape, such that the liquid input from thesecond channel 109 into the scent chamber 105 has a further increasedvelocity when it leaves the end opening of the second channel 109. Insome implementations, the output end opening of the second channel 109is close to the output end opening of the third channel 110. As aresult, the fragrance output via the second channel 109 is fullyatomized by the air flow from the third channel 110, and can beextensively distributed in the scent chamber 105.

When the fragrance is a liquid with relatively high viscosity, such asan essential oil, the liquid tends to adhere to the wall of the channel.As time passes by, the path for the scent to flow may becomeincreasingly narrow, which affects scent-producing efficiency. In someembodiments, as shown in FIG. 2C, the internal bottom surface of thescent chamber 105 is not set to be a horizontal plane, but a surfaceinclined towards the inlet of the first channel 108 so as to form afunnel shape near the inlet of the first channel 108. This way, theliquid fragrance suspended on the inner wall of the scent chamber 105can return into the fragrance container 107, thereby saving thefragrance. Therefore, the high-velocity air flow can fully atomize thefragrance in the embodiments in accordance with the techniques disclosedherein. Moreover, the fragrance that is not fully atomized may stay onthe inner wall of the scent chamber 105 and ultimately flow back intothe fragrance container.

In some embodiments, referring to FIG. 2D, the path of the fourthchannel 111 includes a check valve 125. In some embodiments, the candledevice further includes an inclination sensor 124, as shown in FIG. 4 .When the candle device is tilted, the inclination sensor 124 can sensethe tilt and then shut down the power supply to the air pump 106. Theair pressure in the scent chamber 105 then quickly decreases to shutdown the check valve 125.

When the candle device is tilted or inverted, it is possible for theliquid fragrance to flow into the scent chamber 105 through the firstchannel 108, the second channel 109, the fifth channel 115, the sixthchannel 116, and the suction tube 118. The scent chamber 105 acts as abuffer between other channels (e.g., the first channel 108, etc.) andthe fourth channel 111 such that the liquid fragrance needs to beaccumulated to a certain amount in the scent chamber 105 before it canenter the fourth channel 111 and flow out, which requires the candledevice to be tilted or inverted for a relatively long time. In someembodiments, the check valve 125, such as the one shown in FIG. 2D, canstop the fragrance that flows into the fourth channel 111 from leakingout. Furthermore, when the air pump 106 is turned off, the check valve125 is in a closed state to form a sealed space inside of the fourthchannel 111. Therefore, even when the fragrance is in contact with anexternal channel, the check valve 125 ensures that the fragrance willnot flow out of the device. In some embodiments, the inclination sensor124 may include a rolling ball switch, which can be disposed on acircuit board of the candle device or any other places where it can bepositioned. The switch of the inclination sensor 124 can turn on or offthe power supply to the air pump 106, either by hardware circuitry orsoftware control. In some embodiments, an inclination angle thresholdcan be set at, for example, 45 degrees, 75 degrees, or another angle, asthe threshold angle formed between the longitudinal axis of the candledevice and the vertical axis with respect to the horizon. The thresholdcan be used to determine when the inclination sensor 124 should shutdown the power supply to the air pump 106. For example, as shown in theembodiment in FIG. 4 , three inclination sensors 124 are disposed in atriangular manner with respective to each other on a circuit broad. Aninclination angle threshold of 45 degrees or 75 degrees is used suchthat, when the longitudinal axis of the candle device forms an angle,relative to the vertical axis, that is larger than the threshold, thepower supply to the air pump 106 is shut down.

In some embodiments, referring to FIG. 3A, the candle device does notinclude a first channel. Instead, the fragrance goes through the suctiontube 218 and a corresponding second channel 209 into the scent chamber105 directly. In some embodiments, the scent chamber may include, or canbe replaced by, a water-absorbing material 228 at the location where thesuction tube 218, the scent-releasing opening 229, and the seventhchannel 230 meet. The water-absorbing material 228 can be used fortransporting the liquid fragrance in the fragrance container 207 to anexternal environment of the candle device. The water-absorbing material228 includes, but is not limited to, cotton, sponge, etc. Thewater-absorbing material 228 absorbs the liquid fragrance and helps itevaporate into the air. In the embodiment shown in FIG. 3A, a fan 227 isused to accelerate the evaporation of the fragrance. In someembodiments, the air pump 206 may also be used to accelerate theevaporation of the fragrance. Such embodiments as shown in FIG. 3Arequire fewer components, thereby allowing the candle device to besmaller and more compact.

In some embodiments, referring to FIGS. 3B-D, the candle device does notinclude a first channel. Instead, the fragrance goes through the suctiontube 318 and/or a corresponding second channel 309 into the scentchamber directly. In some embodiments, the scent chamber may be replacedby a heating device 331 or an atomizing device 332 at the location wherethe suction tube 318, the scent-releasing opening 328, and the seventhchannel 330 meet. The heating device 331 or the atomizing device 332 canbe used for transporting the liquid fragrance in the fragrance container307 to an external environment of the candle device. In the embodimentsshown in FIGS. 3B-3C, a fan 327 is used to accelerate the evaporation ofthe scent. In some embodiments, as shown in FIG. 3B, the heating device331 heats and helps the fragrance to evaporate. The heat facilitates thefragrance to evaporate more quickly and evenly. In some embodiments, theheating device 331 may also produce smoke during the process of heating,mimicking a visual effect of a real flame. The heating device 331 mayinclude an electric heating wire, a Positive Temperature Coefficient(PTC) heating element, a semiconductor or electromagnetic heatingmodule, and other electric heating elements.

In some embodiments, as shown in FIG. 4 , the electronic candle 100further comprises a smoke generator 131. The smoke generator 131 is usedto further atomize the fragrance and/or additional liquid scent to asmoke. For example, the smoke generator 131 can be the atomizing device332 as shown in FIGS. 3C-3D. The smoke generator 131 works with acontrol circuit 133, and the control circuit 133 can be used to detectactions of a user, such as “blowing off,” “turning off fan,” or “turningoff device.” In some implementations, when the electronic candle 100 isturned on, the smoke generator 131 does not produce smoke. When thecontrol circuit 133 detects an action of “blowing off,” “turning offfan,” or “turning off device,” the control circuit 133 sends a signal tothe control circuitry 132, which controls, according to the signal, thesmoke generator 131 to produce smoke when the electronic candle 100 is“extinguished” to simulate the smoke produced when a real candle isextinguished. In some implementations, the smoke generator 131 may alsocontinuously produce smoke when the electronic candle 100 is turned onso that, when the electronic candle 100 is lit, a scent is released andaccompanied by a smoke to simulate the smoke produced when a real candleis burning. In some embodiments, the smoke (e.g. a thin smoke) producedby the smoke generator 131 is released from the through hole 102. Insome implementations, the shell 101 includes a plurality of holes toallow the smoke to be released.

In some embodiments, the smoke generator 131 is electrically coupled tothe control circuitry 132 to control the smoke generator 131. In someembodiments, the smoke generator 131 is an ultrasonic atomizer. Afterbeing activated by an electric signal, the ultrasonic atomizer produceshigh-frequency harmonic oscillations, which cause a porous metalmembrane adhered to the ultrasonic atomization piece to produceultrasonic vibration through energy transfer, causing the liquidadsorbed to the metal membrane to be atomized. Such smoke generator 131does not require heating or adding a chemical reagent, and thus can bemore energy-efficient than atomization techniques that use heat. Suchsmoke generator 131 also has characteristics such as low noise, longservice life, and low power consumption. The smoke produced by the smokegenerator 131 may appear like real smoke from a real candle. It is notedthat the smoke generator 131 can be implemented using other compatiblesmoke generation structures and techniques that operate basedpressurized atomization, static atomization, ultrasonic atomization,bubble atomization, rotary atomization, annular hole atomization, etc.

In some embodiments, the light-emitting element 112 of the electroniccandle 100 may be an LED lamp. FIGS. 12A-12C show some embodiments inwhich the light emitted by at least one LED lamp illuminates the smokeproduced during the heating process through a through hole. In someembodiments, the smoke can be blown out of the candle device through thethrough hole by the air pump or the fan. The illumination of the LEDlight cast on changing shapes of the smoke can make the flames look likereal flames of a burning candle. In some embodiments, the LED light maybe installed on one side of the flame element 103, such as shown in FIG.12A. In some embodiments, the LED light may be installed on two sides ofthe flame element 103, such as shown in FIG. 12B. In some embodiments,the LED light may be installed on the bottom of a support structure thatsupports the flame element 103, such as shown in FIG. 12C. Thelight-emitting element 112 may also be a halogen lamp, which canfacilitate the evaporation of the fragrance by the heat of the lampitself. The warm color of the halogen lamp and the heated smoke give thecandle device a more appealing appearance of a real burning candle. Insome embodiments, such as shown in FIG. 3C, the atomizing device 332atomizes the fragrance, which is blown out by the air pump or the fan337 such that the fragrance can evaporate more evenly. In anotherembodiment, as shown in FIG. 3C, the atomizing device 332 directlyatomizes the fragrance, which is released into the external environmentby the scent-releasing opening. Embodiments such as the one shown inFIG. 3C require fewer components so that the candle device can be madesmaller and more compact.

In some embodiments, referring to FIGS. 9A-9B, the scent-producingcandle device includes a fragrance container 107, a first channel 108coupled to an air inside the fragrance container 107, and a secondchannel 109 coupled to a fragrance inside the fragrance container 107.The fragrance container 107 can be a bottle containing a liquidfragrance, such as perfume or essential oil. In some embodiments, theair pump 106 pumps air into the scent chamber 105 via the third channel110.

It should be noted the examples described herein include one fragrancecontainer 107 in the scent-producing electronic candle. However, aplurality of fragrance containers 107, for example two, three or morefragrance containers 107, can be used if desired. FIG. 13 shows anexample of a candle device that includes three fragrance containers 107.In some implementations, a plurality of scent chambers can be used sothat each scent chamber is connected to each of the plurality offragrance containers 107. A plurality of fourth channels can beconnected to the plurality of scent chambers to allow the scent to betransported to an external environment. In some implementations, onescent chamber is connected to the plurality of fragrance containers 107.Another channel is connected to the scent chamber to allow the fragranceto be transported to the outside. A user may choose his or her favoritecustomized scent by mixing and matching various fragrance stored in theplurality of fragrance containers. Different scents can either be mixedbefore being sent to an external environment, or be sent to an externalenvironment and then mixed in the air, both of which can further improvethe diversity and the effect of scents.

In some embodiments, referring to FIGS. 10A-10B and FIGS. 11A-11B, anelectronic candle 100 includes a shell 101, a through hole 102 on thetop of the shell 101, a flame element 103 running through the throughhole 102 and extending outwardly from the inside of the through hole102. The inside of the shell 101 is constructed to accommodate afragrance container 107, a first channel 108 coupled to the air insidethe fragrance container 107, and a second channel 109 coupled to afragrance inside the fragrance container 107. The shell 101 may be usedfor installation and fixation of various components inside theelectronic candle 100. For example, the shell 101 may be used to supporta bracket to hold a light-emitting element and a coil for driving aflame piece to sway.

In the specific embodiment shown in FIGS. 11A-11B, the candle device 100includes an accommodating chamber 104 within the shell 101. Thescent-producing mechanism includes a scent chamber 105. The scentchamber 105 further includes a first channel (not shown) and a secondchannel 109. The first channel is constructed to be coupled to the airinside a fragrance container 107, and the second channel 109 isconstructed to be coupled to a fragrance inside the fragrance container107. The scent chamber 105 may also include a third channel 110 and afourth channel 111. The third channel 110 is constructed to input theair to the scent chamber 105, and the fourth channel is constructed tooutput a scent produced in the scent chamber 105 to the outside of theelectronic candle 100. The fragrance container 107 located within theaccommodating chamber 104 can be a bottle containing a liquid fragrance,such as perfume or essential oil. In some embodiments, the accommodatingchamber 104 may also be used to accommodate a container holding a solidfragrance, such as a scent block. In some embodiments, the air pump 106pumps air into the scent chamber 105 via the third channel 110. The airpump 106 can be disposed inside the shell 101. Alternatively, the airpump 106 may also be disposed outside the shell.

Referring to FIG. 11A, in some embodiments, the air enters the scentchamber 105 via the third channel 110. In some implementations, the airpump 106 pumps the air into the third channel 110 such that the airpressure of the scent chamber 105 keeps on increasing. Under the higherair pressure, the air in the scent chamber 105 then enters the fragrancecontainer 107 via the first channel 108, causing the air pressure in thefragrance container 107 to increase as well. The fragrance in thefragrance container 107 is then transported under pressure into thescent chamber 105 via the second channel 109 to be fully atomized.Because the air pressure in the scent chamber 105 is also higher thanthe air pressure of the external environment of the electronic candle100, the atomized fragrance is released via the fourth channel to theoutside of the electronic candle 100. Compared to those embodiments thatinclude a fan to drive the air to produce a scent, the embodiments thatuse an air pump have the following advantages. First, the electroniccandle 100 in accordance with the techniques disclosed herein caneffectively drive a fragrance to the second channel 109 inside theelectronic candle 100 by the air pressure produced by the air pump 106.Meanwhile, the air pressure of the air pump 106 itself can fully atomizea liquid fragrance, which improves the aromatic effect of the fragrance.The atomized fragrance can also appear as smoke produced when the candledevice 100 is “burning.” Second, the atomized fragrance is moreconcentrated as compared to fragrance dispersed using other mechanisms,e.g., a fan. Furthermore, the air pressure produced by the air pump 106is adjustable, thereby allowing the user to adjust the atomization rateof the fragrance. For example, when a fan is used to drive air flow todisperse the liquid fragrance, the magnitude and direction of itspressure acting on the fragrance may not be precisely controlled eventhough the wind speed and direction of the fan can be adjusted. The airpump, on the other hand, can apply air pressure of different magnitudesand directions in a relatively precise manner, thereby achieving moreeffective control by the user. Using the air pump, the atomizedfragrance can appear like a smoke that is produced by a real burningcandle, achieving a more realist look and feel. In some embodiments, theair pump can pump the fragrance at a higher speed to produce a burst ofsmoke so that the candle device appears to be extinguished like a realcandle.

In some embodiments, referring to FIGS. 10A-10B, the shell 101 has anappearance similar to a conventional candle. The cross section of theshell 101 may have a triangular, square, oval, or irregular shape. Theshell 101 may be made of any one of the materials such as wax, paraffin,plastics, glass, metal, ceramic, crystal, and polymers, or anycombination thereof. The top of the shell 101 may be a substantiallyflat surface, or have a recess, to simulate a brand-new unused candle.The shell 101 may also include additional shapes, such as solidifiedflows of melted wax, formed on its surface so as to simulate a usedcandle. The top of the electronic candle 100 includes a through hole102, and the flame element 103 extends outwardly from inside the shell101 via the through hole 102.

In some embodiments, the candle device 100 comprises an accommodatingchamber 104 and a fragrance container 10 positioned in the accommodatingchamber 104. In some embodiments, the fragrance container 107 maypre-installed in the electronic candle 100 during manufacturing orpackaging. In some other embodiments, the electronic candle 100 may notcarry the fragrance container 107. Instead, a user may install it onhis/her own into the accommodating chamber 104 according to his/herpreferences of fragrances.

In some embodiments, the accommodating chamber 104 may have a shape of acuboid or a cube to accommodate a plurality of fragrance containers 107,such as shown in FIG. 13 . In some implementations, the accommodatingchamber 104 may have a shape of a ring such that the plurality offragrance containers 107 are evenly or unevenly distributed along thering-shaped space in the chamber 104.

In some embodiments, one end of the third channel 110 is connected tothe scent chamber 105, and the other end of the third channel 110extends to the through hole 102 to release the scent out of theelectronic candle 100. The shell 101 may include a plurality ofscent-releasing openings disposed at different positions of the shell.In some embodiments, the other end of the third channel 110 may extendto other places of the electronic candle 100. For example, theelectronic candle 100 can be suspended using a support mechanism. Theother end of the third channel 100 may extend to the bottom of anelectronic candle 100 to release scent from the bottom of the candle. Insome embodiments, the support mechanism can be a magnetic levitationmechanism. In some embodiments, one or more additional through hole(s)can be formed at the bottom of the electronic candle to allow convectionof the air and the fragrance in the electronic candle 100 to enable asmoother spray of the scent from the electronic candle 100.

In some embodiments, as shown in FIG. 10A, the upper portion of theflame element 103 has a flame shape and can make irregular movements.When a light is projected onto the flame element 103, the flame element103 randomly sways to simulate of the movements of a real flame. Inaddition, as shown in FIGS. 10A-10B, the flame element 103 includes adark-colored section 123 to simulate a real candle wick after burning.As shown in FIG. 4 , when the control circuit 133 detects one of thefollowing actions of “blowing off,” or “turning off the fan,” or“turning off the device”, the control circuit 133 sends a signal to thecontrol circuitry 132, which controls the smoke generator 131 accordingto the signal to produce smoke when the electronic candle isextinguished to simulate the smoke produced when a real candle isextinguished. At the same time, the flame element 103 may retract, asshown in FIGS. 10A-10B, and the dark-colored section 123 of the flameelement 103 extends outside of the through hole 102 to simulate a realcandle wick after burning. The dark-colored section 123 may still remainoutside of the through hole 102, and/or may slightly rise outside of thethrough hole 102. The flame shape on the upper portion of the flameelement 103 can be a sheet-like flame, or may be combined by two or moresheet-like flames, or may have a 3D shape. In some embodiments, theflame element 103 may be made of plastic or an organic syntheticmaterial. In some embodiments, the flame element 103 is made of atranslucent material, such that the flame can be seen from both sides ofthe flame piece. In some implementations, the flame piece on the upperportion of the flame element 103 has an uneven thickness to simulatelighting effects of a flame at different heights. For example, the flamepiece is thin at the top and thick at the bottom. For another example,the flame piece is thin at the top, thick in the middle, and thin at thebottom. In some embodiments, the flame element 103 includes a pivot hole(not shown). A support element, e.g., a rigid V-shaped rod, goes throughthe pivot hole to support the flame element 103. In someimplementations, the distances between the lowest point of the supportelement and two ends are not equal. The light source 112 can bepositioned at the end that has a shorter distance to allow betterillumination of the flame-shaped portion. The support element may be asoft wire, and two ends of the support element can be fixed to the shell101 such that the flame element 103 can pivot about the support element.In some embodiments, the lower portion of the flame element 103 may havea magnet or a magnetic material, such that the flame element can makenonlinear movements varying with time under the action of the magneticfield. In some embodiments, the flame element 103 is driven by othermechanisms such as air flow (e.g., from a fan) or gas flow from theoutside.

Moreover, as shown in FIG. 4 , the electronic candle 100 furthercomprises a remote control module 136. A user can send an electricsignal to the remote control module 136 using a remote control device.The remote control module 136 receives the electric signal and sends asignal to the control circuitry 132, and the control circuitry 132controls, according to the signal, the electronic candle 100 to turn theelectronic candle 100 on or off and to perform other controls of thedevice.

To enable the air pump 106 and the light-emitting element 112 to operatenormally, the electronic candle 100 further comprises a power supply.The power supply may be formed by providing a battery chamber toaccommodate one or more dry cells or re-chargeable batteries. In thecase of a rechargeable battery, the battery can be charged in a wiredcharging mode. In some embodiments, the power supply may also be chargedin a wireless charging mode. In some implementations, the power supplymay be charged with solar energy; such solar energy is converted intoelectrical energy for storage when the product is not in use, and theelectrical energy can be supplied to the electronic candle 100 duringuse. In some embodiments, the power supply may include a plug that isdirectly connected to an AC outlet so as to supply power to theelectronic candle 100.

Furthermore, as shown in FIGS. 14A-14D, the bottom of the electroniccandle 100 includes a plurality of support components 128 (e.g., legs).The plurality of support components 128 are separated from one anotherby corresponding gaps. As shown in FIG. 14D, a power supply connection129 is formed in the center bottom of the electronic candle 100, where acan be connected to the power supply connection 129. The spacing betweenthe support components 128 allows the power cord to reach the electroniccandle while the electronic candle is placed on a flat surface. The usermay select, according to the desired position and direction of theelectronic candle 100, the appropriate gap for routing the power cord.

In some embodiments, referring to FIG. 13 and FIGS. 14A-14D, the shell101 of the electronic candle 100 includes at least one observationwindow 126 to observe the remaining quantity of fragrance in thefragrance container 107. When there is a plurality of fragrancecontainers 107, the shell 101 includes a plurality of observationwindows 126, each corresponding to one of the plurality of fragrancecontainers 107. In some embodiments, the observation window 126 is madeof a clear plastic. In some implementations, the observation window 126may have a specific shape such as, but not limited to, a rectangle, arhombus, an ellipse, and the like. To allow the user to observe thefragrance under poor lighting situations, in some embodiments such asshown in FIGS. 11B-11C, a light source 127 may be provided in theelectronic candle 100. The light source 127 can illuminate the body ofthe fragrance container 107 such that the quantity of remainingfragrance can be observed.

It is noted that the fragrance container 107 may hold a liquidfragrance. In some embodiments, the fragrant container may also hold ascented bead, a scented block, etc. In some implementations, thefragrance container 107 may simply contain water. When the water isatomized, it can humidify the air and achieve an effect similar to thatof a humidifier.
